I have a 355 with 11 to 1 comp. Canfield heads with an Isky 630 ground on a 110 LSA. I put a 671 and have it 10 % overdriven run it on 112 and dont seem to have any detonation problems . Wide band is green at idle and goes slightly yellow "rich" at WOT. My question is this , would the wide band hint of detonation by going red or could there still be a problem with a good reading?
